Then you're just not laughing hard enough! Lol. Noise is sure to come out if you can laugh hard enough. Ah yes, the snort effect. I have that from time to time too.
That is true! Gosh I only laugh with myself if I read something funny somewhere... But other then that I only find myself really laughing with other people.
I gigglesnort if I read something for a second but if I am having a real good hard laugh no sound comes out. That is how you know if I find something funny or if I'm faking it. If there is sound it's fake but if there is no sound it's real. *nods head*
